PART 2 – PRODUCTS

2.01  NETWORK CAMERA SPECIFICATIONS

A.  GENERAL REQUIREMENTS:

1.  The SNC-CH240 shall be a Full HD fixed-type CS-mount network camera supporting three codecs, JPEG, MPEG-4 and H.264, any two of which can be used simultaneously. The SNC-CH240 shall utilize a 1/2.8-type, Exmor CMOS sensor of approx. 3.27 Megapixels and have a day/night capability.

2.  The SNC-CH240 shall incorporate View-DR (Visibility Enhanced Wide Dynamic Range) technology, to produce images with wider dynamic ranges of up to 90 dB. View-DR shall be a combination of the following three technologies: Full capture Wide-D, Visibility Enhancer (VE) and the high-speed Exmor CMOS. Full capture Wide-D shall expand the video dynamic range of the camera to improve the visibility of images even in extremely high-contrast environments and shall also compensate for scenes with extremely poor contrast.

3.  The SNC-CH240 shall have a Visibility Enhancer (VE) function, which optimizes the brightness and color reproduction of an image dynamically on a pixel-by-pixel basis to provide better visibility in poor backlight conditions.

4.  The SNC-CH240 shall have a feature called XDNR (Excellent Dynamic Noise Reduction), which reduces AGC noise to provide clear images without motion blur. XDNR also reduces image data size.

5.  XDNR and VE can be used in conjunction with each other and shall provide approximately four times the sensitivity compared to the condition where both features are set to off.

6.  The SNC-CH240 shall have an Easy Focus function, which adjusts the camera focus by using the Easy Focus button on the rear of the camera or remotely via the GUI. When the camera is switched between day and night modes, the Easy Focus function is automatically activated to keep the camera focused.

7.  The network interface shall be via an 8-pin RJ-45 connector, 10Base-T /100Base-TX Ethernet. Both IPv6 and IPv4 are supported.

8.  The SNC-CH240 shall utilize JPEG, MPEG-4 and H.264 compression. There are two ‘resolution’ modes to choose from when installing a camera: 1920 x 1080 (Full HD) (default) or 1920 x 1440.


When 1920 x 1080 mode (aspect ratio: 16:9) is selected, and resolutions in 4:3 aspect ratio are chosen, the displayed image will be stretched vertically. When 1920 x 1440 mode (aspect ratio: 4:3) is selected, and resolutions in 16:9 aspect ratio are chosen, the displayed image will be stretched horizontally.

9.  The supported resolutions in 1920 x 1080 and 1920 x 1440 mode are shown in the following tables:


10. The maximum frame rate capability of the SNC-CH240 over LAN at 1920 x 1080 resolution shall be 30 frames per second in H.264, 25 frames per second in MPEG-4 and 15 frames per second in JPEG. The maximum frame rate at 1920 x 1440 resolution shall be 20 frames per second in H.264, 15 frames per second in MPEG-4 and 10 frames per second in JPEG.

11. The SNC-CH240 shall have the capability of simultaneously encoding up to two of the following codecs in any combination: JPEG, MPEG-4, and/or H.264 including multiple instances of the same codec.
The maximum frame rates of each combination are shown in the table below:

12. JPEG compression levels shall be user selectable in ten (10) levels of compression ratios, based on an image of 24bits per picture element (8bits each for YUV).

13. Constant bit rate algorithm for JPEG data:
The SNC-CH240 shall be capable of equalizing JPEG data sizes to have stable bandwidth utilization. Data size for each compression level is as follows:

14. Actual frame rate in JPEG shall be shown in the table below:



15. The SNC-CH240 shall have an analog video output producing 600 TV lines of horizontal resolution when the camera is in 1920 x 1440 mode (4:3 aspect ratio).

16. The supported operating systems shall be Microsoft Windows 7™ 32bit (Ultimate/Professional), Windows Vista® 32bit (Ultimate/Business), Windows® XP 32bit (Professional), and DirectX® 9.0c or higher. Minimum PC requirements shall be the Intel Core®2 Duo Processor, 2 GHz or higher, with 2GB RAM or more supporting 1600 x 1200 or higher resolution (2560 x 1600 resolution or higher is recommended), 24-bit True Color display capability with Ethernet 100Base-TX.

17. The SNC-CH240 shall incorporate a built-in web server, such that the standard web browser Microsoft® Internet Explorer (version 6.0, 7.0 or 8.0 recommended) can be used to access the camera without need for special viewer software.

18. The following web browsers can also be used to access the camera with the ‘Plug-in Free’ viewer: Firefox version 3.5, Safari version 4.0 and Google Chrome version 4.0. When using these browsers, the video is displayed in JPEG format.

19. The ‘Plug-in Free’ viewer also supports the Flash plug-in and ActiveX viewer, the latter allowing for MPEG-4 and H.264 video streams.

20. The SNC-CH240 shall support ActiveX viewer which allows the camera image to be viewed in Internet Explorer. The ActiveX viewer allows for recording of video and audio directly to the PC’s hard drive, and supports direct audio from the PC mic to the camera.

26. The SNC-CH240 shall have the capability to stream MPEG-4 and H.264 video in TCP protocol or MPEG-4 and H.264 in UDP (unicast/multicast) protocol.

27. The SNC-CH240 shall have an Adaptive Rate Control (ARC) function when using MPEG-4 and H.264 compression. This function when enabled, shall allow the camera to maintain the frame rate at a reduced image quality when network congestion occurs. Should network bandwidth become further restricted, the frame rate shall then drop automatically to a suitable speed to maintain image integrity.

28. The SNC-CH240 shall incorporate a built-in Intelligent Motion Detection (IMD) capability. To minimize false triggers, the SNC-CH240 IMD shall compare the current image with prior 15 frames within the camera. The IMD algorithm shall allow the camera to discriminate against some environmental noise such as shaking leaves or AGC noise.

29. The camera shall incorporate Sony’s Distributed Enhanced Processing Architecture (DEPA™) Advanced technology whereby the IMD function can be used with built-in Video Motion Filters (VMF) to trigger alarms based on rules. The camera shall have the following five VMFs, all of which can be set from the camera setup menu:

a.  Appearance filter: detects objects that match the detection criteria for objects entering into a user defined area.

b.  Disappearance filter: detects objects that match the detection criteria for objects exiting a predefined area.

c.  Existing filter (Loitering filter): detects an object that stays within a defined area longer than the set limit.

d.  Capacity filter: triggers an alert when the number of detected objects meets or exceeds the detection criteria for object number within the configured area.

e.  Passing filter or virtual borders: detects objects crossing the set virtual borderline, going in either direction or a specified direction.

30. The SNC-CH240 shall have an audio detection function, which detects loud sounds via an external microphone to trigger alarms or camera actions. The SNC-CH240 shall compare the detected sound with the threshold learned from ambient noise and the frequency to minimize false triggers. The sensitivity settings shall be Low, High and Manual (1 to 100).

31. The SNC-CH240 shall have a camera tampering detection function that alerts the operator if the camera is tampered with. Tampering can include spraying the camera lens, covering it with a cloth, or changing the mounting direction.

32. The SNC-CH240 shall be capable of electronic pan/tilt/zoom, or so called ‘Solid PTZ’.
